CONCRETE RAILROAD-TIE.

Specification of Letters Patent.

Patented se t. 10,1912.

Application filed January 24, 1912. Serial N o. 673,198;

To all whom it may concern Be it known that I, ALLEN T. Soon, a citizen of the United States, residing at South Be-llingham, in the county of Whatcom and State of Washington, have invented a new and useful. Concrete Railroad- Tie, of which the following is a specification.

The object of the present invent-ion is to provide a composite railroad tie, consisting of a concrete body and suitable reinforcing elements, the construction being such that the constituent members of the tie may readily be assembled, to hold the rail.

A further object of the invention is to provide a composite railroad tie, the reinforcing elements of which give maximum strength, with minimum expenditure of material.

With the foregoing and other objects in view, which will appear as the description proceeds, the invention resides in the combination. and arrangement of parts and in the details of construction hereinafter described and claimed, it being understood that changes in the precise embodiment of invention herein disclosed can be made within the scope of what is claimed without departing from the spirit of the invention.

In the drawings,Figure 1 shows in top plan, a railroad tie constructed in accordance with the present invention; Fig. 2 is a perspective of one of the reinforcing members; Fig. 3 is a fragmental side elevation of the element shown in Fig. 2; Fig. 4 is a transverse section on the line 44 of Fig.1; Fig. 5 is a perspective showing a modified form of the invention; and Fig. 6 is a top plan of the tie shown in Fig. 5.

In carrying out the invent-ion there are provided a pair of channel members, de-

noted generally by the numeral 1, the channel members being preferably of H-shape in cross section. The channel members 1 include vertical, primary side flanges 2 connected by a web 4, intermediate the upper and lower edges of the flanges 2. Adjacent their ends, the flanges 2 are equipped, at their upper ends, with rail-receiving shoulders 5, projecting beyond both sides of the flanges 2. Upon the shoulders 5 there .are rail-holding fingers 6, all of which extend in a common direction. The flanges 2 are pierced, upon both sides of the web 4, with .ments will thus be effected.

a series of openings 11. Through the flanges 2 above the web 4, there is aline of openings 14. Of these openings '14 there may be any desired number. The webs '4 are pierced with a series of .openingsl5 preferably, although not necessarily, extending the. full length of thetie. The channels are embedded in concrete 16 so that the upper faces of the shoulderso are flush with the upper face of the concrete. A pair if members constructed as above described, may be placed side by side, the fingers 6 of one member extending in an opposite direction from the fingers 6 of the adjoining member, so as to engage both edges of the rail 17 as clearly shown in Fig. 1. Through any of the openings 14, preferably those at the extreme end of the tie, bolt and nut connecv tions 18 may be inserted, so as to hold the constituent members of the tie together. The concrete 16 will, obviously, fill the openings 11, 12, 15, and likewise fill those openings 14 which are not encumbered-by the securing bolts 18. A secure bond between the concrete and the reinforcing ele- Moreover, by piercing the reinforcing elements with the plurality of openings, as above described, the. tie is lightened, and the amount of material employed is obviously new, with a corresponding reduction in cost.

In Figure 5, a modified form of the invention is shown. In this form of the invention, the reinforcing elements are denoted generally by the numeral 20, and include primary vertical flanges 21, from both sides of which project the secondary horizontal flanges 22. The upper edges of the flanges 21 are equipped with rail-receiving shoulders 24, projecting beyond both sides of the flanges 21, the shoulders 24 being equipped with cooperating, rail-holding fingers 25. In the flanges 22 there are openings 26, and in the flanges'21 there are openings 27, locatedupon both sides of the sec ondary flanges 22. The reinforcing members above described may be embedded in concrete as shown at 28, the two constituent elements of the tie being held together by means of bolts 29, passing through the openings 30, corresponding to the openings 14 of Fig. 3. As in the preferred form of the invention, the upper face of the shoulders 24 are flush with the upper face of the concrete.

Having thus described the invention, what is claimed is 1. A railroad tie comprising a pair of reinforcing members, each including a vertical primary flange and a horizontal secondary flange projecting laterally from the primary flange, intermediate the upper and lower edges of the primary flange, the secondary flanges being in horizontal alinement; the primary flanges of both reinforcing members being equipped, adjacenttheir. ends, with integrally formed railreceiving shoulders projecting beyond both sides of the primary flanges and extended downwardly upon the opposed side faces of. the primary flanges, the shoulders being equipped with rail-engaging fingers; means for securing the reinforcing members together; and a concrete body assembled with each reinforcing member.

2. A railroad tie comprising a pair of reinforcing members, each having a vertical primary flange and a horizontal secondary flange projecting laterally from the primary flange, intermediate the upper and lower edges of the primary flange, the secondary flanges being in horizontal alinement and both flanges being of equal length; each primary flange being equipped, adjacent its ends, with integrally formed railreceiving shoulders, projecting beyond both sides of the primary flange and extended downwardly upon opposed side faces of the sides of the primary flange and extended fingers upon the shoulders; the primary flanges and the secondary flanges being pierced by a series of openings concretereceiving; a concrete body assembled with each reinforcing member; and securing elements extended through certain of the openings in the primary flanges. to constitute a means for holding the reinforcing members together.

3. A tie comprising a pair of concrete members; an H-shaped reinforcing element embedded within each member, both of the vertical flanges of each H-shaped element being provided with integrally formed, laterally extended, rail-receiving seats, there being rail-holding fingers located at the 0 ends of the seats, all of the fingers projecting in a common direction in each H- shaped element and projecting in opposite directions in the two H-shaped elements.

In testimony that I claim the foregoing as my own, I have hereto aflixed my signature in the presence of two witnesses.
